Quit Intentions and Attempts among Smokers in Sub-urban Nepal: Findings from the Dhulikhel Heart Study.

Background The most effective way for smokers to avoid or minimize the harmful effects is to quit smoking. Smoking cessation has been attributed to multiple factors operating at physiological, psychological, environmental and social level. There is common consensus that smoking cessation programs should be tailored for specific populations. However, there has been lack of data regarding factors that influence smoking cessation in Nepal, which has hindered the development of effective smoking-cessation interventions. Objective To assess the prevalence of quit attempts, successful quitting and the factors associated with them in a randomly selected, population-based adult participants in sub-urban Nepal. Method This cross-sectional study utilized data from the first wave of the baseline survey of the Dhulikhel Heart Study (DHS). A total of 2225 households of Dhulikhel city were enumerated and a third of the households (n=735) were randomly selected. Questions on tobacco use were ascertained using the questions based on the WHO STEPS survey questionnaire and questions on past quit attempts. Result Out of 1073 participants, 248 (23.1%) were current smokers and 99 (9.2%) were former smokers. Only 58% of the current smokers mentioned that they had attempted to quit smoking. When asked if they were interested in quitting if helped, almost 90.5% mentioned they were willing. Brahmins were less likely to have quit smoking (former smoker) compared to Newars (OR: 0.41, 95% CI: 0.18-0.90). We also observed that those who had high alcohol consumption were less likely to have quit smoking (OR: 0.36, 95% CI: 0.17-0.76). We didn't find any meaningful significant association between socio-demographic factors or other CVD risk factors and the quit attempts. Conclusion As the country braces to address the burden of non-communicable diseases in Nepal, it is crucial to incorporate tobacco cessation programs in the national health system to meet the global target of bringing tobacco consumption to less than 5% by 2040. We recommend future studies to get a broader understanding of quit effort and factors associated with thereby supporting the development of evidence-based strategies to address tobacco cessation.

Prevalence and Correlates of Tobacco Use in a Suburban community of Nepal: Findings from the Dhulikhel Heart Study.

Background Smoking and oral tobacco use are important risk factors for cancer and other chronic diseases. The distribution of tobacco consumption in Nepal varies across the population subgroups. There is little information on the correlates of tobacco use among suburban population in Nepal. Objective To estimate the prevalence of smoking and oral tobacco use; and determine the socio-demographic and other CVD risk factors associated with them in a suburban population of Dhulikhel, Nepal. Method This cross sectional study utilized data from the first wave of the baseline survey of the Dhulikhel Heart Study (DHS). A total of 2225 households of Dhulikhel city were enumerated and a third of the households (n=735) were randomly selected. Questions on tobacco use were ascertained from 1073 adults age 18 years and older using the questions based on the WHO STEPS survey questionnaire. Result More than a third (36%) of the men were current smokers and 12% reported regular use of oral tobacco. About 14% of the women were current smokers and only 0.5% reported to use oral tobacco regularly.In the multivariate analysis, sex, ethnicity, education, alcohol consumption and body mass index were significantly associated with tobacco use. Males were 2.6 times as likely as females to smoke (95%: 1.53-4.59; p<0.001). Brahmin/Chhetri were 2.8 times more likely to smoke compared to Newars (95% Ci: 1.53-5.18; p=0.001). Education reduced the odds of smoking; compared to those with no formal education, those with up to high school and those with a high school degree or higher were 0.50 (95% CI: 0.27-0.92; p=0.02 ) and 0.38 (95% CI: 0.16-0.91; p=0.03) percent less likely to smoke, respectively. Moderate drinkers were 8 times more likely (95% CI: .54 - 18.40; p<0.001) and high drinkers were 13 times (95% CI: 6.63 - 24.26; p<0.001) compared to non-drinkers. Regarding oral tobacco use males were 15 times as likely as females to use oral tobacco (95% CI: 4.1-58.8; p<0.001). Compared to Newars, Brahmin/Chhetri were 2.7 times as likely to use oral tobacco (95% CI: 1.08 - 6.66; p=0.03). Conclusion Although Nepal has made some progress in passing progressive laws for tobacco control, and national surveys have shown slight reduction on tobacco use, this is far from satisfactory to meet the global target of bringing tobacco consumption to less than 5% by 2040. We recommend future studies to focus on socio-cultural, gender and behavioral aspects of tobacco use in addition to the epidemiological aspects.
